Seven departments will be renamed in the overhaul, two new departments established and three abolished, according to government changes gazetted on Friday.

One director-general, Frankie Carroll, has already elected to depart the public service following the overhaul.

It is understood Mr Carroll - who had been serving as Deputy Premier Jackie Trad's top bureaucrat - was offered the Department of State Development, Manufacturing, Infrastructure and Planning director-general's job before announcing he would leave.

Another director-general, Paul Simshauser, announced his departure during the election campaign, while Environment director-general Jim Reeves is retiring.

National Parks, Sport and Racing director-general Tamara O'Shea is also rumoured to be retiring next year.
